VAPOR VACU'UM HEATING SYSTEM.

Specification of Letters Patent.

Patented July 25, 1916.

Application filed April 28, 1914. Serial N 0. 835,033.

To all whom it may concern:

Be it known that I, BANKsO. DAUBERT, a citizen of the United States, residing at Norfolk, in the county of Madison and State of Nebraska, have invented new and useful Improvements in Vapor Vacuum Heating Systems, of which the following is a specification.v

The invention relates to a heating apparatus, and more particularly to the class of vapor-vacuum heating systems.

The primary object of the invention is the provision of an apparatus of this character wherein two systems of pipes are employed, one a radiator supply system and the other a return system from the radiator to the generator, the return system being fitted with a separator which permits the escape of air fromall of the radiators to the atmosphere and the condensation conveyed to the generator of the system so that the need for air valves on the radiators is obviated.

Another object of the invention is the provision of a heating system of this character wherein a saving in fuel is had and at the same time a rapid and high heat can be attained, the system being readily and easily controlled in moderate weather.

A further object of the invention is the provision of a heating system of this character wherein the separating tank with the cooperative valves will not allow the water to escape from the system or any of the steam or vapor therefrom.

A further object of the invention is the provision of a system wherein the air conveyed from the radiators will be prevented from returning or getting back into the sys tem after being once driven out.

A still further object of the invention is the provision of a system of this character wherein the water of condensation and the air will be received by the return system so that the air can be expelled to the atmosphere and the water of condensation delivered to the generator so that the eiiiciency of the system is assured With economy in the consumption of fuel 'and resultant maximum heat generation.

Other objects will be in part obvious and in part hereinafter pointed out.

The invention accordingly consists in the construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicatedin the following claim.

In the drawings:Figure l is a diagrammatic view of a heating system constructed in accordance with the invention. Fig. 2 is a vertical longitudinal sectional view through the separator showing the valves cooperative therewith in vertical section. Fig. 3 is a fragmentary vertical sectional view through the return pipe from the separator to the generator.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A designates generally a furnace having a vapor head or steam dome B which communicates with the boiler of the furnace. At the desired points are arranged radiators C which are connected with the generator of the furnace A by means of a supply system or main D having branches E leading to the radiators, and each branch is provided with a regulating valve F of any approved form for controlling the supply from the generator to the radiator. Leading from the radiator C are the branches G of a return system H which is connected with a separating device presently described.

The separating device comprises a cylindrical receiver or tank 10, the return system H being in communication therewith through one end of the same, while leading from this tank 10 is a water return pipe 11 which is coupled with the drip pipe 12 of the supply system or main D leading to the generator, the pipes 11 and 12 being pro vided with swinging check valves 13 and 14 respectively. Arranged within the tank 10 is a spherical float 15 formed with a guide stem 16 Working within a column 17, the stem 16 being slidable through guides 18 fitted within the column 17, while connected with the said column 17 is an elbow pipe 19, the latter communicating with a ther- In-ostatic valve casing 20 from which leads an elbow pipe 21 having a valve casing 22, the said pipe 21 being extended exteriorly of a building forcommunication with the atmosphere, and within the valve casing 22 thereof is a normally seated valve 23 so that air from the radiators C can escape to the atmosphere through the pipe 21 on the opening of the valve 23 in a manner hereinafter fully described.

It will be noted that the valve 28 and the casings 22 of the pipe 21 will permit the es cape of air from the separator 10 to the atmosphere, but will prevent the entrance of air from the atmosphere to the return system H of the apparatus. The pipe 11 will permit the flow of the water of condensation from the separator 10 to the generator of the furnace A, but should the water in the generator rise the same will be shut off from the separator 10 by the check valve 13 in the pipe 11 leading from the said separator to the pipe 12 of the system D to the generator.

It is of course understood that the generator and supply systems are provided with gages 24 and 25 respectively, of any preferred form or construction, and also that the doors and dampers may be controlled by an automatic draft check or regulating device if desired.

In the operation of the apparatus, after starting a fire in the furnace A, the thin bodies of water pass over the heated surface of the boiler and begin to absorb the heat, the

1 vapor produced within the boiler begins to rise to the steam dome, and it passes into the supply main or system D to the branches E,

and thence into the radiator through the inlet valve F, which when regulated controls the supply to the radiators. As the vapor enters the radiators the air therein is rapidly forced ahead of the vapor, which makes its way through the return system H, and also the air and condensation is caused to travel through the return system to the separating tank 10, and after the water of condensation reaches the latter the same will flow through the return pipe 11 against the check valve 13 therein, leaving the air to pass out through the thermostatic valve casing 20 to the pipesQl and thence to the atmosphere.

The stem 16 of the float 15 within the tank 10 is surrounded by means of a valve 26 which is adapted to engage a seat 27 at the inner end of the column 7 on the rising of the float within the separator under certain conditions. b

After the cold radiators are filled with vapor it begins to condense into water, which with the air passes through the return system H into the separator tank 10, and the water therein backs up from the check valve 13 into the separating tank, thus causing the float 15 to rise and its valve 26 will close the column 17, thus increasing a few ounces of pressure and difference in elevation above the water line of the boiler within the furnace and thereby causing the opening of the check valve 13, allowing all Copies of this patent may be obtained for five cents each, by addressing the of the condensation to pass from the separating tank 10 to the boiler in the furnace 10. lVhen the condensation has all passed out of the separating tank 10 the float 15 drops to its normal position and again allows the air from the return system 8 and derived from the radiators to pass to the atmosphere. Now, on operating the valves F in the branches E of the supply system, should through carelessness more steam or vapor enter the said radiators the same will be conducted tothe separating tank, thence to the thermostatic valve casing 20, thus operating the valve therein, thereby closing off the escape of the steam to the atmosphere. Now, after all air has passed out from the system the valve 23 closes the pipe 21 and in event of the fire becoming low the vapor condenses and creates a vacuum in the system and thus exerts a constant suction on the boiler within the furnace, and in this mannor the vapor will lift the steam into the radiators so that maximum heat is maintained within the system under various conditions.

From the foregoing it is thought that the construction and manner of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is In combination with a vapor vacuum heating system and a furnace, said system including a plurality of radiators and a supply ipe connecting said radiators with the boiler of the furnace, of a return pipe having connection with said radiators, a drip pipe for connecting the supply pipe to the boilerbelow the water level and having a check valve, a cylinder having connection with the end of the return pipe, a pipe connecting the cylinder with the drip pipe and having a check valve, a column rising the cylinder and projected into the latter to form a valve seat, a float arranged within the cylinder and having a stem working within the column, a valve formed at the juncture of the stem with the float and engageable with the valve seat, an outlet pipe leading from said column, a thermostatic valve arranged in said outlet pipe, and a check valve located in said outlet pipe to prevent back flow therein to the cylinder.

In testimony whereof I affix my signature in presence of two witnesses.
